Two men have been charged with the murder of the aspiring athlete at a London Underground station.
Tashan Daniel, 20, was fatally stabbed at Hillingdon Underground Station on September 24 after being attacked while heading to to an Arsenal football match.
British Transport Police have since said that Alex Lanning, 21, from Uxbridge, and Jonathan Camille, 19, from Kensington, had both been charged with his murder.
The pair have been remanded in custody and are due to appear at Highbury Magistrates' Court on Monday.
An 18-year-old woman, from West Drayton, who was arrested on suspicion of assisting an offender has been released under police investigation.
Police previously said that Mr Daniel, who had hoped to become an international 200m sprinter, was with a friend when two other men provoked a fight, during which he was knifed in front of horrified passengers.
Witnesses reported seeing blood and one person performed CPR on the victim but he died on board a Tube carriage.
The Underground station was evacuated in the wake of the stabbing.
Speaking previously about the investigation when the two men were first arrested, Detective Chief Inspector Sam Blackburn said: 'We have been working around the clock to trace those responsible for Tashan's death and this is a positive step in the ongoing investigation.
'I'd like to thank Tashan's family for their patience and strength and once again extend our deepest condolences to them. They are continuing to be supported by specially trained family liaison officers.
'I know the local community and many people across the country have been truly shocked by this senseless and unprovoked killing, and we will continue to work tirelessly to make sure those responsible face justice.'
His mother Celia Daniel, 48, earlier told of how she was able to 'hold his hand for a tiny second' while paramedics worked on him.
Before the match, his family said he had lunch with his mother and took his grandfather to a day care centre.
His father told the BBC: 'He was short on time - he ruffled my hair, gave me a kiss on the cheek and that's the last time he left home.'
He added: 'Tashan wanted to make the Olympics. He set his standards high, he was hardworking and did everything we asked him to.
'He was a real family-orientated boy and he was a beautiful soul.'
Luke Flynn, a colleague and former schoolmate of Mr Daniel, said: 'He will be missed my his friends family and work colleagues.
'He was really involved in his track running. I'm pretty sure he was one of the better runners in the UK. He was always doing it every weekend. He was doing really well in the 100m and 60ms.
'He was a nice guy, quiet, and just got on with his work. It's sickening. It's horrible to hear, he was such a nice guy, he was always up for helping. Everyone was taken aback when they heard.'
A spokesman for Arsenal FC said: 'Everyone at Arsenal Football Club is shocked and deeply saddened to learn of the tragic passing of Arsenal fan Tashan Daniel.
'Our thoughts are with Tashan's family and friends at this sad time.'
